Description

Technical Field

[0001] The utility model belongs to the technical field of rubber products, and particularly relates to a rubber anti-collision block assembly for mechanical equipment. Background Art

[0002] The existing common anti-collision block assembly mainly includes the block body itself and the installation structure. Among them, the above installation structure can be an additional accessory or an extended part of the block body itself. For example, an extended part in the shape of a "hook" can be used to hook and fix the entire anti-collision block assembly.

[0003] Among them, the material of the above block body itself is generally various low-elasticity and high-strength rubbers, such as natural rubber, and the above accessories generally include bolts. Thus, the anti-collision block assembly made of this rubber material can achieve a sufficient and stable anti-collision protection effect.

[0004] For example, the Chinese utility model patent with the authorization announcement number CN210949636U and the authorization announcement date of July 7, 2020 discloses a silent magnet rubber anti-collision block, which includes an anti-collision block body. The anti-collision block body includes a base, an adsorption surface and a limiting side surface that are integrally connected. The adsorption surface is vertically arranged at one end of the base, and limiting side surfaces perpendicular to the base are symmetrically arranged on both sides of the adsorption surface. A plurality of buffer bumps in the shape of hemispheres are arranged on one side of the cross beam.

[0005] The general advantages of the rubber anti-collision block in this utility model patent are as follows: high strength and durability; the two limiting side surfaces clamp the magnet, the guiding surface of the limiting inner hook edge facilitates the pushing of the magnet, and the limiting surface clamps and positions the magnet. Combined with the buffer bumps inside the cross beam, good buffer protection is provided during each adsorption collision of the magnet.

[0006] However, when this rubber anti-collision block is actually used on mechanical equipment, there are at least the following two deficiencies, which are also the technical problems to be solved by this utility model, that is:

[0007] First, its clamping installation method cannot provide relatively large installation stability. When the moving part of the mechanical equipment hits the anti-collision block relatively frequently and forcefully, the anti-collision block is likely to fall off;

[0008] Second, its adsorption window structure greatly damages the structural integrity of the anti-collision block, resulting in its inability to provide relatively strong buffer effect, which is not allowed for relatively large mechanical equipment.

[0009] Therefore, in summary, there is an urgent need for a new type of rubber anti-collision block assembly with stable installation and strong buffer effect to be used on various relatively large mechanical equipment. Summary of the Utility Model

[0010] The present utility model provides a rubber anti-collision block assembly for mechanical equipment. By arranging two countersunk holes and two mounting bolts on a trapezoidal block, and ensuring that the central axis distance between the two countersunk holes is ≥ 60% of the length of the trapezoidal block, the following effects can be achieved: 1. The assembly can be stably installed on the mechanical equipment through the two mounting bolts; 2. Most of the solid area between the two countersunk holes can provide relatively large buffering strength.

[0011] The technical solution adopted by the present utility model to solve the above problems is: a rubber anti-collision block assembly for mechanical equipment, the structure of which includes a trapezoidal block, two countersunk holes arranged on the trapezoidal block, and mounting bolts arranged on the countersunk holes, and the central axis distance between the two countersunk holes is ≥ 60% of the length of the trapezoidal block.

[0012] A further preferred technical solution lies in that: a fastening nut is also provided on the mounting bolt.

[0013] A further preferred technical solution lies in that: on the inner ring surface of the blind hole part of the countersunk hole, a protruding block is provided for blocking the head of the mounting bolt or the fastening nut.

[0014] A further preferred technical solution lies in that: the shape of the protruding block is circular.

[0015] A further preferred technical solution lies in that: the shape of the protruding block is rectangular.

[0016] A further preferred technical solution lies in that: on one end surface in the length direction of the trapezoidal block, a storage groove is provided for placing the fastening nut in the idle state.

[0017] A further preferred technical solution lies in that: a protruding column for inserting the fastening nut is provided in the storage groove.

[0018] A further preferred technical solution lies in that: on the other end surface in the length direction of the trapezoidal block, a slot for placing a nameplate is provided.

[0019] A further preferred technical solution lies in that: a nameplate insertion rod groove is provided on the bottom surface of the slot.

[0020] A further preferred technical solution lies in that: the number of the protruding columns is two. Description of the Drawings

[0034] The following is only a preferred embodiment of the present utility model, and does not limit the scope of the present utility model.

[0035] As shown in the Figures 1 - 10 accompanying drawings, a rubber anti-collision block assembly for a mechanical device, the structure includes a trapezoidal block 1, two countersunk holes 2 provided on the trapezoidal block 1, and a mounting bolt 3 provided on the countersunk holes 2, and the central axis distance between the two countersunk holes 2 is ≥ 60% of the length of the trapezoidal block 1.

[0036] In this embodiment, the material of the trapezoidal block 1 is natural rubber, which has the advantages of wear resistance, high strength, aging resistance, tear resistance, etc., and is suitable for manufacturing anti-collision blocks.

[0037] Among them, the above-mentioned "trapezoid" refers to the following two slightly different specific structures:

[0038] First, only the two sides corresponding to the width of the trapezoidal block have their upper ends close to each other;

[0039] Second, the upper ends of all four side faces corresponding to the width of the trapezoidal block and the length c of the trapezoidal block are close to each other.

[0040] The wording "upper end" mentioned above refers to the end where the blind hole portion of the countersunk hole 2 is located, which is also the direct buffer end of the anti-collision block.

[0041] On the other hand, the two countersunk holes 2 are as far away as possible on the trapezoidal block 1, so as to make the effective buffer area between the two countersunk holes 2 larger, and finally improve the buffer strength of the anti-collision block. For details, please refer to the attached Figure 10 The cushioning strength provided by the rubber area outside the two countersunk holes 2 in the length c direction of the trapezoidal block can be ignored.

[0042] The mounting bolt 3 is also provided with a fastening nut 4 .

[0043] In this embodiment, when a threaded hole is provided on the mounting plate g, the fastening nut 4 is used together with the mounting bolt 3; when a threaded groove is provided on the mounting plate g, the fastening nut 4 is left unused.

[0044] The above two methods do not affect the stable installation effect and high-strength buffer effect of the trapezoidal block 1.

[0045] A protruding block 5 for blocking the head of the mounting bolt 3 or the fastening nut 4 is provided on the inner annular surface of the blind hole portion of the countersunk hole 2 .

[0046] In this embodiment, the protruding block 5 has the following two functions:

[0047] First, when the assembly is stored and transported, the fastening nut 4 is placed outside the head of the mounting bolt 3 and inside the protruding block 5. Thus, the fastening nut 4 and the mounting bolt 3 are not easy to fall off the trapezoidal block 1, and can even be prevented from loosening, which ultimately facilitates the installation of the assembly without having to look for the scattered fastening nut 4 and mounting bolt 3.

[0048] Second, when the assembly is installed and used, even if the mounting bolt 3 is accidentally loosened and leaves the mounting plate g, it will fall off together with the trapezoidal block 1 and is unlikely to fall out of the countersunk hole 2, thus facilitating the retrieval of the anti-collision block assembly. Of course, if the fastening nut 4 is used at this time, the fastening nut 4 does not have the above-mentioned anti-falling function.

[0049] The protruding block 5 is in the shape of a circular ring.

[0050] In this embodiment, the size of the head of the mounting bolt 3 is similar to that of the fastening nut 4. The annular protruding block 5 has an appropriate radial thickness and is slightly stuck on the falling-out path of the mounting bolt 3 and the fastening nut 4, ensuring that the anti-fall-out function is effective and that the resistance is moderate when the fastening nut 4 is actively taken out.

[0051] The protruding block 5 and the trapezoidal block 1 are integrally formed, or can be a rubber block with greater elasticity installed later.

[0052] The protruding block 5 is in the shape of a rectangle.

[0053] In this embodiment, when the protruding block 5 is rectangular, its function and principle are the same as those of the above-mentioned annular protruding block 5.

[0054] One of the end faces of the trapezoidal block 1 in the length direction is provided with a receiving groove 6 for accommodating the fastening nut 4 in an idle state.

[0055] In this embodiment, the end surface is not within the main buffering area of the anti-collision block, so the buffering strength of the anti-collision block is substantially not affected after the receiving groove 6 is provided.

[0056] When the anti-collision block assembly is stored and transported, the receiving groove 6 is idle, and when the assembly is installed and used normally and the fastening nut 4 is not needed, it can be idle in the receiving groove 6 or put back into the countersunk hole 2.

[0057] However, the idle storage effect of the latter is required, that is, it cannot interfere with or affect the already tightened mounting bolts 3. Therefore, the storage method of placing it at the storage groove 6 is better.

[0058] The receiving groove 6 is provided with a protruding column 7 for inserting the fastening nut 4 .

[0059] In this embodiment, the protruding column 7 is a cylinder, and it does not matter whether a thread is provided on it. Thus, when the mounting bolt 3 is used with the thread groove, the unused fastening nut 4 is not easily lost.

[0060] The other end face of the trapezoidal block 1 in the length direction is provided with a slot 8 for placing a nameplate a.

[0061] In this embodiment, the nameplate a is used to distinguish and name each anti-collision block, so that the inspection personnel and the maintenance personnel can communicate more quickly during the subsequent maintenance work.

[0062] For example, the nameplate a may be marked with: Three-Punch 2-Bottom, indicating that the anti-collision block assembly is one of several anti-collision blocks under the second punching machine in the third workshop, which saves a lot of communication costs.

[0063] A nameplate insertion rod groove 9 is provided on the bottom surface of the slot 8.

[0064] In this embodiment, the function of the nameplate insertion rod groove 9 is to stably install the nameplate a sufficiently.

[0065] Among them, the total slotting depth of the slot 8 and the nameplate insertion rod groove 9 is still less than that of the storage groove 6. The above slotting positions are all at the ends of the trapezoidal block 1 and not in its effective buffering area in the middle, so the buffering strength is not affected.

[0066] The number of the protruding columns 7 is two.

[0067] In this embodiment, the two protruding columns 7 correspond to the two fastening nuts 4.

[0068] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the purpose of the present invention. These are all non-creative modifications and are protected by the Patent Law as long as they are within the scope of the claims of the present invention.
